As his fold to 3bet is low I think you can raise more preflop for value say to 19.50. I think it's +ev to make these non standard plays vs this villain. I would be double barrelling here then re-assess his play if he raises the turn. As you haven't bet the turn you have no idea on his hand range and he could be betting out anything as you have cbet & checked the turn. You under rep your hand here and make it look like a standard cbet with an Ax type hand. This could also be good vs this spewy player and get him to put more money in the pot with air. Does the small bet on the turn mean anything to you? For example, has he bet small with strong hands or when he triple barrel bluffed with air did he bet small or big?

I'd be betting bigger on the flop about 2/3 of pot, $55-70ish on turn then it sets up shove on river. Just sucks if he has TT/JJ./AA but I think you are getting called by a lot worse by someone who's bluff catching with 99-77.

What Adam said. Mix in a 50nl table with your usual tables. If not concentrate and just 2 table while you are learning the differences between stakes. I've moved from 180's to start grinding 25nl. I'm building a bankroll and I think there is a big difference between 25nl and 50nl too. If you mix in a small amount of tables of 50nl then I definitely think it is beatable and mainly just a game of confidence.

Limping is just telling people you having small pocket pair. I will raise any two PF to a reg limping and then cbet the flop. Any sign of strength they will usually have a set and I can fold.

I agree with raising, I never limp unless I am deep and know that I won't get raised in late position. Otherwise, raise small, 10/20 level I'm fine with a raise of 45-60 and we can fold to a 3bet if we don't have setmining odds.

15/30 raise to 70ish, 25/50 depending on stack sizes and PP I raise or fold. For example, I will open fold 22-77, 88 I raise to 125. This is just a bit of theory, but it all depends on players left to act and stack sizes, but I'm never open folding a pocket pair on first level, irrelevant of my position.
